Process of producing stock food.



UNITED STATES PATENT OFFICE.

JOSEPH STEI-ILIN, OF NEW YORK, N. Y.

PROCESS OF PRODUCING STOCK FOOD.

No Drawing.

T 0 all whom it may concern Be it known that I, JOSEPH STEHLIN, acitizen of the United States of America, residing at Manhattan borough,city, county, and State of New York, have invented certain new anduseful Improvements in Processes of Producing Stock Food, of which thefollowing is a full, clear, and exact description.

My invention relates to a process for producing animal or stock food andhas for its object to utilize what has heretofore been a waste product,so that same may become a valuable article of commerce for use as anutritive food for cattle or other live stock.

In producing animal or stock food by my improved process, I utilize whatare known as spent hops, that is to say, hops which have been used inbreweries in the manufacture of malt liquors and which have heretofore,after such use, been a waste product and of little or no valuecommercially. Such waste or spent hops, after having gone through thebrewing stages are in a highly saturated or moist condition; and incarrying out my invention, the spent hops are first placed in suitablepresses to extract excess moisture,whereupon the spent hops are driedand partially cooked or steamed in suitable apparatus of well knownconstruction, the drying being effected to such an extent thatsufficient. moisture is eliminated to avoid subsequent decomposition ofthe product. I find that drying to an extent whereby about eight percent. moisture remains, is most satisfactory. After the drying has takenplace, the stems of the spent hops are or may be eliminated therefrom,although the removal of the stems is not absolutely necessary. Thereupon the dried spent hops are ground or Specification of Letters Patent.

triturated into powder form, in which condition the product is suitablefor use as animal or stock food. Before feeding live stock therewith,the aforesaid food is mixed with water or other suitable liquid.

Having now described my invention,what I claim and desire to secure byLetters Patent is:

1. The herein described process of pro ducing live stock food,comprising first extracting excess moisture from spent hops, thereupondrying the same until about eight per cent. moisture remains, and thenreducing the product to powder form.

2. The herein described process of producing stock food, comprisingextracting excess moisture from spent hops, drying the same, removingthe stems from the hops, and trit-urating the resultant product.

3. The herein described process of producing live stock food, comprisingextracting excess moisture from spent hops, partially cooking and dryingthe same, and reducing the mass to powder form.

4. The herein described process of producing stock-food, comprisingextracting moisture from spent hops, and partially cooking and dryingthe same.

5. The herein described process of pro ducing stock food, consisting infirst extracting excess moisture from moist spent hops, thereupon dryingthe same until about eight per cent. moisture remains, partially cookingand drying the same, and reducing the product to powder form.
